Abstract
Availability of effective antiretroviral therapy (ART) has improved patient survival and older adults (≥50 years old) constitute 10% of the world's HIV population. However, data on this population are lacking, especially in sub-Saharan Africa. To identify the profile of older adults with HIV infection receiving ART and factors associated with viral suppression. A retrospective cross-sectional study involving HIV patients ≥50 years, registered at a University Hospital in Kumasi, Ghana from January 2010 to July 2020. All study participants had been on ARTs for ≥12 months. Data were analysed using STATA® and multivariate logistic regression was done to determine the association between variables. We recruited 132 study participants with a mean age of 58.1 years (±6.8). Non-communicable diseases (NCD) comprised the commonest comorbidity (67.4%; n = 89) and hypertension was the most prevalent (47.2%). The mean duration of ART was 63.2 months (±32.0) and approximately 84.1% (n = 111) achieved viral suppression (≤50 copies/ml). After adjustment, factors independently associated with viral suppression were widow(ed) (aOR = 0.23; 95% CI = 0.07-0.72) and good ART adherence (aOR = 3.51; 95% CI = 1.03-11.99). Hypertension is prevalent among this cohort of HIV patients. Approximately 84% of elderly patients on ARTs achieve viral suppression, influenced by widowhood and good drug adherence.

Analytical Treatment Interruption after Short-Term Antiretroviral Therapy in a Postnatally Simian-Human Immunodeficiency Virus-Infected Infant Rhesus Macaque Model. mBio 2019; 10:e01971-19. [PMID: 31488511 PMCID: PMC6945967 DOI: 10.1128/mbio.01971-19] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2019] [Accepted: 08/05/2019] [Indexed: 12/27/2022] Open
Abstract
To achieve long-term viral remission in human immunodeficiency virus (HIV)-infected children, novel strategies beyond early antiretroviral therapy (ART) will be necessary. Identifying clinical predictors of the time to viral rebound upon ART interruption will streamline the development of novel therapeutic strategies and accelerate their evaluation in clinical trials. However, identification of these biomarkers is logistically challenging in infants, due to sampling limitations and the potential risks of treatment interruption. To facilitate the identification of biomarkers predicting viral rebound, we have developed an infant rhesus macaque (RM) model of oral simian-human immunodeficiency virus (SHIV) SHIV.CH505.375H.dCT challenge and analytical treatment interruption (ATI) after short-term ART. We used this model to characterize SHIV replication kinetics and virus-specific immune responses during short-term ART or after ATI and demonstrated plasma viral rebound in 5 out of 6 (83%) infants. We observed a decline in humoral immune responses and partial dampening of systemic immune activation upon initiation of ART in these infants. Furthermore, we monitored SHIV replication and rebound kinetics in infant and adult RMs and found that both infants and adults demonstrated equally potent virus-specific humoral immune responses. Finally, we validated our models by confirming a well-established correlate of the time to viral rebound, namely, the pre-ART plasma viral load, as well as identified additional potential humoral immune correlates. Thus, this model of infant ART and viral rebound can be used and further optimized to define biomarkers of viral rebound following long-term ART as well as to preclinically assess novel therapies to achieve a pediatric HIV functional cure.IMPORTANCE Novel interventions that do not rely on daily adherence to ART are needed to achieve sustained viral remission for perinatally infected children, who currently rely on lifelong ART. Considering the risks and expense associated with ART interruption trials, the identification of biomarkers of viral rebound will prioritize promising therapeutic intervention strategies, including anti-HIV Env protein therapeutics. However, comprehensive studies to identify those biomarkers are logistically challenging in human infants, demanding the need for relevant nonhuman primate models of HIV rebound. In this study, we developed an infant RM model of oral infection with simian-human immunodeficiency virus expressing clade C HIV Env and short-term ART followed by ATI, longitudinally characterizing the immune responses to viral infection during ART and after ATI. Additionally, we compared this infant RM model to an analogous adult RM rebound model and identified virologic and immunologic correlates of the time to viral rebound after ATI.

HIV cause-specific deaths, mortality, risk factors, and the combined influence of HAART and late diagnosis in Zhejiang, China, 2006-2013. Sci Rep 2017; 7:42366.

Abstract
To examine patterns of human immunodeficiency virus (HIV) cause-specific deaths, risk factors, and the effect of interactions on mortality, we conducted a retrospective cohort study in Zhejiang, China, from 2006 to 2013. All data were downloaded from the acquired immune deficiency syndrome (AIDS) Prevention and Control Information System. The Cox proportional hazards model was used to assess predictors of cause-specific death. The relative excess risk due to interaction and ratio of hazard ratios (RHR) were calculated for correlations between HAART, late diagnosis, and age. A total of 13,812 HIV/AIDS patients were enrolled with 31,553 person-years (PY) of follow-up. The leading causes of death of HIV patients were accidental death and suicide (21.5%), and the leading cause of death for those with AIDS was AIDS-defining disease (76.4%). Both additive and multiplicative scale correlations were found between receiving HAART and late diagnosis, with RERI of 5.624 (95% CI: 1.766-9.482) and RHR of 2.024 (95% CI: 1.167-2.882). The effects of HAART on AIDS-related mortalities were affected by late diagnosis. Early detection of HIV infection and increased uptake of HAART are important for greater benefits in terms of lives saved.

Abstract
UNLABELLED Background Multimorbidity is the co-occurrence of more than one chronic health condition in addition to HIV. Higher multimorbidity increases mortality, complexity of care and healthcare costs while decreasing quality of life. The prevalence of and factors associated with multimorbidity among HIV positive patients attending a regional sexual health service are described. METHODS A record review of all HIV positive patients attending the service between 1 July 2011 and 30 June 2012 was conducted. Two medical officers reviewed records for chronic health conditions and to rate multimorbidity using the Cumulative Illness Rating Scale (CIRS). Univariate and multivariate linear regression analyses were used to determine factors associated with a higher CIRS score. RESULTS One hundred and eighty-nine individuals were included in the study; the mean age was 51.8 years and 92.6% were men. One-quarter (25.4%) had ever been diagnosed with AIDS. Multimorbidity was extremely common, with 54.5% of individuals having two or more chronic health conditions in addition to HIV; the most common being a mental health diagnosis, followed by vascular disease. In multivariate analysis, older age, having ever been diagnosed with AIDS and being on an antiretroviral regimen other than two nucleosides and a non-nucleoside reverse transcriptase inhibitor or protease inhibitor were associated with a higher CIRS score. CONCLUSION To the best of our knowledge, this is the first study looking at associations with multimorbidity in the Australian setting. Care models for HIV positive patients should include assessing and managing multimorbidity, particularly in older people and those that have ever been diagnosed with AIDS.

Abstract
OBJECTIVES The objective of this study is to evaluate the impact of therapeutic HIV vaccination on the HIV reservoir and assess the relationship of the viral reservoir with HIV-specific immune status and viral rebound kinetics. DESIGN A retrospective analysis of ACTG A5197, a randomized, placebo-controlled trial of a therapeutic rAd5 HIV-1 gag vaccine. METHODS Participants received vaccine/placebo at weeks 0, 4 and 26 prior to a 16-week analytic treatment interruption (ATI) at week 38. Cell-associated HIV-1 RNA and DNA (CA-RNA and CA-DNA) and HIV-1 residual viremia were quantified at weeks 0, 8 and 38. HIV-specific CD4(+)/CD8(+) activity was assessed by an intracellular cytokine staining assay. RESULTS At study entry, CA-RNA and CA-DNA levels were correlated inversely with the numbers of HIV-specific CD4(+) interferon-γ producing cells (CA-RNA: r = -0.23, P = 0.03 and CA-DNA: r = -0.28, P < 0.01, N = 93). Therapeutic HIV vaccination induced HIV-specific CD4(+) activity, but did not significantly affect levels of CA-RNA or CA-DNA. Vaccine recipients with undetectable residual viremia at week 8 had higher frequencies of HIV-specific CD4(+) and CD8(+) interferon-γ producing cells (undetectable versus detectable residual viremia: 277 versus 161 CD4(+) cells/10(6) lymphocytes, P = 0.03 and 1326 versus 669 CD8(+) cells/10 lymphocytes, P = 0.04). Pre-ATI CA-RNA and CA-DNA were associated with post-ATI plasma HIV set point (CA-RNA: r = 0.51, P < 0.01 and CA-DNA: r = 0.47, P < 0.01). CONCLUSION Vaccine-induced T-cell responses were associated with a modest transient effect on residual viremia, but more potent immune responses and/or combination treatment with latency-reversing agents are needed to reduce the HIV reservoir. HIV reservoir measures may act as biomarkers of post-ATI viral rebound kinetics. CLINICAL TRIALS REGISTRATION NCT00080106.
